CLP stands for the ”Compact Linked Piston”. No more compact than inline engines,
but extremely compact versus previous linked pistons.

It uses linked pistons and is best arranged as an L4 (linked four cylinders). The
CLP is one of many ”alternative” engine ideas, however this one uses conventional
and known engine philosophies and relationships, only the head piston legs are unrecognisable.

Notes on the CLP:

The; piston crowns, cylinders, crankshafts, conrods, assembly, ancillaries and valvetrains
all remain the same or almost the same.

With a linked piston there is much less scraping and lunging and more sliding and
slipping because the piston is five times longer, and therefore runs stabilised in
its cylinder.
